Though I would have to say that Pwn463^† of Ms. Shlaes is like shooting fish in a barrel:

When you hear claims that the New Deal made the depression worse, they often come directly or indirectly from the work of Amity Shlaes, whose misleading statistics have been widely disseminated on the right.

…

Krugman then goes to show that Shlaes is suggesting that actions based on Keynes theories failed to contain unemployment in the 1960s.

Yes, I was unaware of the historically high unemployment rates in the 1960s too.

Just go read… A few hundred words, and he destroys her.
